Modulized wave filter

Abstract

A wave filter includes a circuit board, and a shell housing the circuit board; the circuit board includes a band-pass wave-filtering circuit, and a low-pass wave-filtering circuit; the shell has an input end and an output terminal thereon, which are connected to the band-pass wave-filtering circuit of the circuit board; the shell further has an output end thereon, which is connected to the low-pass wave-filtering circuit; thus, the wave filter is modulized; the wave filter is fitted in a multimedia wideband router, and in turn it is not necessary to change wave filters in order for allowing the multimedia wideband router to be connected to and used with televisions or various digital multimedia equipments.
